Delete Push Registrations for Mobile Devices
Where: This change applies to Lightning Experience, Salesforce Classic, and all versions of the mobile app in all Editions.
How: After revoking a refresh token for a user, delete push registrations for each user as well. In the record detail page for the user, go to Mobile Push Registrations and View all devices.
Delete each registered device for the application the token was revoked for to ensure that push notifications are no longer sent to the user.
